The Impact of International Visiting Scholars Programmes on Nursing PhD Students: An Integrative Review

ABSTRACT

Aim

To explore the impact of international visiting scholars programmes on the academic and professional development of nursing PhD students and to inform future doctoral curriculum design.

Design

Integrative review.

Methods

A systematic search was conducted across six databases (Embase, Medline, CINAHL, ERIC, Scopus and Web of Science) in December 2024, with no restrictions on publication year. After removing duplicates, 1300 records were screened by title, abstract and full text. Studies were included if they focused on nursing PhD students participating in international visiting programmes and addressed academic or professional development. Five studies met the inclusion criteria. Data were synthesised using a thematic analysis approach.

Results

Four themes were identified: (1) advancing academic excellence through enhanced research skills and critical thinking; (2) cultivating cross-cultural learning by fostering cultural sensitivity and adaptability; (3) fostering global networks that promote sustained international collaboration; and (4) shaping doctoral education by encouraging structured and sustainable international experiences. These findings suggest that international visiting scholars programmes contribute meaningfully to the academic, cultural and professional growth of nursing PhD students.

Conclusion

International visiting scholars programmes provide a unique platform for doctoral nursing students to strengthen their academic foundations and expand their global outlook. Integrating such experiences into doctoral curricula can better prepare future nursing leaders for international health challenges.

Impact

This review addresses a gap in the literature by focusing on the doctoral-level outcomes of international visiting scholars programmes in nursing. The findings offer guidance for educators and policymakers to design curricula that integrate global engagement, build institutional support for mobility programmes and promote equitable access to international academic opportunities in nursing education.

Reporting Method

The review adhered to the EQUATOR and PRISMA guidelines for systematic reviews.

Por: Kibone · W. · Muzoora · C. · Bongomin · F. · Namiiro · M. A. · Ssenkungu · S. · Ochola · E. · Kasirye · P. · Hamer · D. H.
Background

Sickle cell disease (SCD) is associated with significant mortality and morbidity, especially in low- and middle-income countries.

Objectives

We determined the indications for hospitalisation and predictors of 30-day re-admission among patients with SCD in Northern and Central Uganda.

Design

Retrospective chart review.

Setting

Mulago National Referral Hospital in Kampala, St. Mary’s Hospital Lacor in Gulu and Gulu Regional Referral Hospital in Gulu, Uganda.

Participants

Patients with confirmed SCD admitted between January 2020 and January 2025 were included.

Outcomes

Primary outcome: indication for hospitalisation. Secondary outcomes: rate and predictors of 30-day hospital re-admission. Socio-demographic, clinical history and hospitalisation data were extracted using a pretested data extraction tool.

Results

We enrolled 505 patients, accounting for 714 hospital admissions, with a mean age of 8.1±6.2 years. Most participants (n=489, 96.8%) had less than four admissions per year, with a median of 1 admission (IQR: 0–2). The most common indications for hospitalisation were infection (n=375, 52.5%), painful crisis (n=366, 51.3%) and anaemia (n=186, 26.1%). Malaria was the most prevalent infection (n=244, 65%). The median length of hospital stay was 4 days (IQR: 3–6), with a 30-day re-admission rate of 6.9% (n=49). Admission with painful crisis (adjusted OR (AOR): 0.45, 95% CI: 0.23 to 0.89, p=0.021), receiving a blood product (AOR: 0.32, 95% CI: 0.16 to 0.66, p=0.002) and having four or more admissions per year (AOR: 0.84, 95% CI: 0.04 to 0.17, p

Conclusions

Infections, especially malaria, and painful crises were the leading causes of hospitalisation among Ugandan patients with SCD. Frequent admissions, painful crises and blood transfusions were associated with lower 30-day re-admission risk. There is an urgent need to strengthen malaria prevention strategies and optimise access to disease-modifying therapy, such as hydroxyurea, to improve patient outcomes.

Understanding preconception care: a scoping review of knowledge, attitudes and practices among reproductive age individuals, healthcare workers and stakeholders in low- and middle-income countries

Por: Aynalem · Y. A. · Paul · P. · Kung · J. Y. · Hussain · A. · Lassi · Z. · Meherali · S.
Objectives

This scoping review aims to map existing evidence on knowledge, attitudes and practices (KAP) and barriers to preconception care in low- and middle-income countries. The primary objective is to identify key gaps and research priorities to guide future efforts to improve maternal and child health.

Design

This review followed Arksey and O'Malley’s scoping review framework, with a comprehensive search across Medline, EMBASE, CINAHL and Scopus from inception to May 2025. Eligible studies included original research on preconception care (PCC), KAP in low- and middle-income countries (LMICs) without date restrictions. Two independent reviewers conducted screening in Covidence. Findings were presented in graphical, tabular and narrative formats, adhering to the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols Extension for Scoping Reviews (PRISMA-ScR) standard.

Setting

The review focused on PCC studies conducted in LMICs across various healthcare settings, emphasising primary and secondary levels of care. The geographical scope was global but limited to LMICs as defined by World Bank criteria.

Result

A total of 62 studies were included in the review. Of these, 42 employed quantitative methods, 18 used qualitative approaches and 2 used a mixed-methods design. Regarding focus areas, 25 studies assessed knowledge, 14 assessed practices, 12 studies assessed KAP comprehensively and 10 assessed attitudes. Participants were mainly women of reproductive age (44 studies), with only five studies including men. Among healthcare providers, KAP varied, with midwives being the most frequently studied group. Stakeholders such as policymakers were notably under-represented. Identified barriers included limited training, cultural beliefs and inadequate policies. Facilitators highlighted were targeted education, spousal support and policy advocacy, emphasising the need for gender-sensitive and systemic interventions.

Conclusion

LMICs face complex challenges in utilising PCC, influenced by socioeconomic, cultural, and healthcare system factors. To address these challenges, nuanced approaches incorporating intersectional perspectives and practical qualitative methodologies are essential for improving couples' and child health outcomes.

Trial registration number

The study protocol was registered in the Open Science Framework (OSF) on December 23, 2022, with DOI: 10.17605/OSF.IO/H3MK6.

Global prevalence of chronic kidney disease and associated risk factors in children and adolescents: protocol for a systematic review and meta-analysis

Por: Hedin · E. · Tungsanga · S. · Ye · F. · Kung · J. Y. · Okpechi · I. · Dart · A. B. · Thompson · S. · Morgan · C. · Erickson · R. · Chaturvedi · S. · Hariramani · V. K. · Crowshoe · H. · Bello · A. K.
Introduction

While chronic kidney disease (CKD) is well characterised in adults, less is known about the prevalence of CKD in children and adolescents, where it is rare and associated with unique characteristics and implications for long-term health outcomes. This study protocol outlines a systematic review to assess the global prevalence of CKD in children and adolescents along with causes and associated risk factors. This is warranted to better characterise prevalence and to identify at-risk groups that would benefit from screening efforts. We will explore the risk and burden of CKD and its variations by sociodemographic characteristics (age group, race, sex/gender) and geographical regions (country, International Society of Nephrology region and income groups based on World Bank country classifications).

Methods and analysis

We will conduct a systematic review of studies reporting on the prevalence of CKD in children and adolescents following the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols 2015 (PRISMA-P-2015) and the PRISMA 2020 methodological guidelines (PRISMA 2020). Searches will be undertaken in the following databases with the date range from 2000 to date: Ovid MEDLINE, Ovid Embase, CINAHL, Cochrane Library, ProQuest Dissertations & Theses Citation Index (via Clarivate), Web of Science Core Collection, Google Scholar and grey literature sites (registries, government reports) to identify studies that report on the prevalence of CKD in children and adolescents from ages 0 to 18. The primary outcome will be the global prevalence of CKD in children and adolescents. Secondary outcomes will include the causes of and risk factors for CKD, and examining differences and temporal trends in CKD prevalence across countries, geographical regions, income levels and sociodemographic characteristics.

Ethics and dissemination

No direct involvement with patient data will be used in this systematic review, as data will be obtained from previously published reports. Ethical approval is therefore not required. Our findings will be published in an open-access peer-reviewed journal and presented at scientific conferences.

Introduction

There have been previous initiatives to identify key performance indicators (KPIs) for continuous kidney replacement therapy. However, no formal reviews of the evidence for KPIs of intermittent kidney replacement therapy (IKRT) have been conducted. This systematic review will appraise the evidence for KPIs of IKRT in critically ill patients and is part of the DIALYZING WISELY (NCT05186636) programme which aims to improve the performance of acute renal replacement therapy in intensive care units by aligning local practices with evidence-based best practices.

Methods and analysis

Ovid MEDLINE, Ovid Embase, CINAHL and Cochrane Library will be searched for studies involving KPIs for IKRT. Grey literature will also be searched and include technical reports, practice guidelines and conference proceedings as well as websites of relevant organisations. We will search the Agency of Healthcare Research and National Quality Measures Clearinghouse for IKRT-related KPIs. Studies will be included if they contain KPIs, occur in critically ill patients and are associated with IKRT. We will evaluate the risk of bias using the modified Cochrane tool and certainty of evidence using the Grading of Recommendations, Assessment, Development and Evaluations methodology. The analysis will be primarily descriptive. Each KPI will be evaluated for importance, scientific acceptability, usability and feasibility using the four criteria proposed by the United States Strategic Framework Board for a National Quality Measurement and Reporting System. Finally, KPIs will be appraised for potential operational characteristics, potential to be integrated into electronic medical records, adoptability by stakeholders and affordability, if applicable.

Ethics and dissemination

Ethics approval is not required as primary data will not be collected. Findings of this review will be disseminated through peer-related publication.

CD11c+ dendritic cells PlexinD1 deficiency exacerbates airway hyperresponsiveness, IgE and mucus production in a mouse model of allergic asthma

by Lianyu Shan, Mojdeh Matloubi, Ifeoma Okwor, Sam Kung, Mohamed Sadek Almiski, Sujata Basu, Andrew Halayko, Latifa Koussih, Abdelilah S. Gounni

Dendritic cells (DCs) are pivotal in regulating allergic asthma. Our research has shown that the absence of Sema3E worsens asthma symptoms in acute and chronic asthma models. However, the specific role of PlexinD1 in these processes, particularly in DCs, remains unclear. This study investigates the role of PlexinD1 in CD11c+ DCs using a house dust mite (HDM) model of asthma. We generated CD11c+ DC-specific PlexinD1 knockout (CD11cPLXND1 KO) mice and subjected them, alongside wild-type controls (PLXND1fl/fl), to an HDM allergen protocol. Airway hyperresponsiveness (AHR) was measured using FlexiVent, and immune cell populations were analyzed via flow cytometry. Cytokine levels and immunoglobulin concentrations were assessed using mesoscale and ELISA, while collagen deposition and mucus production were examined through Sirius-red and periodic acid Schiff (PAS) staining respectively. Our results indicate that CD11cPLXND1 KO mice exhibit significantly exacerbated AHR, characterized by increased airway resistance and tissue elastance. Enhanced mucus production and collagen gene expression were observed in these mice compared to wild-type counterparts. Flow cytometry revealed higher CD11c+ MHCIIhigh CD11b+ cell recruitment into the lungs, and elevated total and HDM-specific serum IgE levels in CD11cPLXND1 KO mice. Mechanistically, co-cultures of B cells with DCs from CD11cPLXND1 KO mice showed significantly increased IgE production compared to wild-type mice.These findings highlight the critical regulatory role of the plexinD1 signaling pathway in CD11c+ DCs in modulating asthma features.

Health and care workers in long‐term care facilities and their role in preventing emerging infectious diseases: A scoping review

Abstract

Background

The COVID-19 pandemic has had a tremendous impact on healthcare systems worldwide. In particular, long-term care facilities have proved more susceptible to infection as they care for vulnerable populations at high risk of chronic illness. How this impacts the role and core competencies of health and care workers in these facilities remains less understood.

Aim

Describe how health and care workers contribute to the prevention of emerging infectious diseases in long-term care facilities.

Design

A scoping review.

Methods

A systematic search of literature dating from 2002 to 2022 was conducted in the following databases: EMBASE, Medline (Ovid), Cochrane Library, CINAHL Plus with Full Text (EBSCOhost), Web of Science, and AgeLine. Studies were selected if they focused on health and care workers in long-term care facilities, offered a perspective on the prevention of emerging infectious diseases or infection prevention and control, and were original qualitative or quantitative studies in English. Data were extracted, cross-checked and analyzed by two researchers, and any difference in views regarding the appropriateness of literature would be resolved by consulting a third researcher. An inductive descriptive approach was applied for the analysis of results, and themes were established via consensus meetings.

Results

A total of fourteen studies from Asia, Europe, and the Americas were included. Three themes emerged from the review: “The roles of health and care workers evolve with the times”, “The core competencies of health and care workers are essential for preventing emerging infectious diseases in long-term care facilities” and “The key to successful prevention of emerging infectious diseases in long-term care facilities is through a systematic, comprehensive effort that mobilize health and care workers at all levels”. Health and care workers had to take on increasingly complex roles and rely on their core competencies to cope with epidemic changes, and facility resources, employee quality and management models were found to have significantly improved infection prevention and control outcomes.

Conclusions

The roles of health and care workers are evolving, and effective infection prevention within long-term care facilities depends on their ability to perform core competencies with skill and confidence. Moreover, a systematic, comprehensive framework, for which this paper proposes three guidelines, is urgently needed to ensure consistent policy implementation within the facility as well as support and access to resources for health and care workers.

Clinical Relevance

Infection prevention efforts within long-term care facilities must take into account the evolving roles of health and care workers, with a focus on guaranteeing access to resources, training and support that will help them gain the core competencies necessary for juggling those roles. In addition, there is an urgent need for research instruments that will help assess those competencies and identify areas of improvement.
